I really like the 2nd pic. The colors and clarity of the photo make it stand out. I like the 3rd as well. Personally, the 1st pic had too much empty space and the subject looked like specks.
Here's my attempt at editing your 1st pic... a tighter crop would help bring everything into focus rather than looking like specks.
I think #2 is awesome! How did you do that? I'm just learning and seeing what gear was used and aperture, speed, ISO, tripod, etc. helps a ton. Beautiful shot.
